Please use the best settings you can, minimum recommended settings are 16bit 44.100khz WAV.
Do not use standard recording techniques!
Do not adjust the preamp on your recording device to boost sound levels, it will destroy the binaural effect and add extra noise that will spoil your recordings.
Do not use MP3 format it will remove some aspects of the "HRTF" (head related transfer function) information and be less effective.
For YouTube I use 24bit or 16bit 96khz WAV recordings and export the audio with AAC 96khz.
For HD sound, please use 24bit 192khz WAV
Uploading to YouTube/soundcloud with content?
Please check that your authoring software is using the best audio quality settings it can use for exporting, using WAV or AAC 96khz, or just use the same audio settings that your recorder used for the actual recording.
For the very best binaural audio experience try not to boost audio levels within your software or modify it by using equalizers or normalising.
Playback is just as important as the recording technique, you must keep the levels of audio to a level of what it would be if you were there. For example if you were to remove your headphones the sound would be the same level as what it was while monitoring the recordings, you should not be able to tell any difference, if it's louder you need to be sure that it is either the recording level, or the volume level of the recorder, once you have established the correct levels in both the recording level and the output volume level of your recording device it is calibrated correctly.
Some listeners may think that the levels are too low as they are used to standard recording/listening habits. When you have realised this technique you will enjoy very effective binaural recordings.
